Selection of short-term fattening season and object for Mutton Sheep

Mutton has high nutritional value: the protein content of mutton is as high as 8% Mel 9.5%, and the digestibility after human consumption is as high as 90%. Mutton can provide a lot of heat, more than twice as much as pork. So mutton has long been favored by consumers.

The short-term fattening of mutton sheep in autumn refers to an effective measure to improve the individual weight, slaughtering rate and economic benefit of commercial sheep by house feeding and adding high-quality forage grass 3 months before sale.

First, to make preparations before fattening whether the short-term fattening of mutton sheep can achieve obvious results or not, the preparation before fattening is very important. At least the following preparations should be made:

1. Because the preparation of the sheep house is to be raised in the house, there must be a sheep shed, with a feeding density of 0.4 million per sheep and 0.5 square meters, in order to restrict the movement of sheep and increase the fattening effect. The location of the sheep house should be convenient for ventilation, drainage, daylighting, shelter from the wind and sun, and close to the pasture and feed warehouse.

2. Preparation of forage and fodder forage and fodder are the basis for fattening sheep. During the whole fattening period, each sheep should prepare 2 Mel 2.5 kg of hay, or 3 Mel 5 kg of silage, or 3 Mel 5 kg of ammoniated feed, etc., while concentrate should be prepared according to 0.3 kg per sheep per day.

3. The choice of fattening season because mutton is mostly used to make mutton hot pot, while "mutton hot pot" is eaten in winter and spring, so the market demand for mutton is the greatest in winter and spring, and it is more suitable for commercial sheep to be fattened in winter. therefore, the fattening season of mutton sheep is the best in autumn, and the temperature is suitable, and the forage grass and crop straw are rich, which is conducive to the rapid growth and sale of mutton sheep.

4. the choice of fattening sheep generally speaking, the sheep used for fattening should choose the lambs and young sheep of the same year, followed by the elimination of sheep and old sheep. After the fattening sheep are selected, the following work should be done:

(1) deworming: because sheep's internal and external parasites are very common, it will seriously affect the normal growth of goats.

(2) castration: the ram used for fattening must be castrated, because the castrated ram has gentle temperament, good meat quality and fast weight gain.

(3) weighing regularly and recording, that is, weighing fattening sheep before and after fattening, in order to evaluate the fattening effect and sum up experiences and lessons.

Second, master the principles of feeding and management

The main results are as follows: 1. Although the coarse concentrate feed can make full use of the roughage than the sheep, in order to improve its daily gain during the fattening period, a certain amount of high-energy feed must be given. The proper ratio of concentrate to roughage can not only provide energy, but also meet the needs of protein, but also maintain the normal activity of rumen and ensure the health of sheep.

2. The proportion of protein in sheep diet should be about 8%.

3. Feeding amount and feeding method the feeding amount of sheep should be determined according to their feed intake. Its feed intake is related to sheep breed, age, sex, physique, feed palatability and moisture. The greater the feed intake of sheep, the higher its daily gain. The daily feed intake of sheep for hay, fresh grass and concentrate is 2 Mel 2.5 kg, 3 Mel 4 kg and 0.3 Mel 0.4 kg respectively. The feeding method is to feed concentrate first, then hay or coarse feed, and finally drink water. Forage is added at any time to maintain the strong appetite of sheep and increase their food intake.

4. The daily management method is mainly to reduce the exercise and consumption of sheep as much as possible, so that all the nutrients absorbed by sheep can be used to gain weight. Fattening in autumn, you can put the sheep out to bask in the sun at noon or graze nearby for a short time.

Short-term fattening must be supplemented with concentrate, and a reasonable mix of concentrate can achieve the effect of less material and faster weight gain.

It should be noted that the seed feed should not be ground too fine, so as not to affect the health of the sheep inhaled into the lungs. In addition, when the concentrate is matched with green hay, it is best to add silage to supplement the need for vitamins, or add multivitamins and trace elements appropriately.
